Question

Arianna is experimenting with different materials to see which one will transmit

sound the fastest. Through which of the following materials will sound waves
travel the fastest?

A. Concrete
B. Air
C. Water
D. Oil

Answer 1

B

Step-by-step explanation:

Sound waves travel fastest through air, as air is the most compressible of all the materials listed. Concrete is the least compressible and thus sound waves travel the slowest through it. Water and oil are both more compressible than concrete, but still less so than air and therefore sound waves travel faster through air than through either water or oil.
